Abstract

Un tubo de metal 1 tiene una sección transversal cuadrangular. El tubo de metal 1 incluye un par de paredes laterales 11 y 12 enfrentadas entre sí y que tienen una altura H, una porción superior 13 conectada a un borde superior de cada una de las par de paredes laterales 11 y 12, y una porción inferior 14 conectada a un borde inferior de cada par de paredes laterales 11 y 12. El tubo de metal 1 tiene una longitud seis veces mayor que la altura H de las paredes laterales 11 y 12 o más. Cada uno de los pares de paredes laterales 11 y 12 incluye una porción de resistencia alta 11A ó 12A y un par de porciones de resistencia baja 11B ó 12B. Cada porción de resistencia alta 11A ó 12A tiene una dimensión no menor que (2/3) H y no mayor que 3H de conformidad con se mide en la dirección longitudinal del tubo de metal, las porciones de resistencia alta que forman porciones opuestas del par de paredes laterales 11 y 12, cada porción de resistencia alta tiene un límite de elasticidad no menor que 500 MPa. Las porciones de resistencia baja 11B ó 12B intercalan entre sí la porción de resistencia alta 11A ó 12A según se determina a lo largo de la dirección longitudinal del tubo de metal, teniendo cada porción de resistencia baja un límite de elasticidad del 60 al 85% de la de la porción de resistencia alta 11A ó 12A.A metal tube 1 has a quadrangular cross section. The metal tube 1 includes a pair of side walls 11 and 12 facing each other and having a height H, an upper portion 13 connected to an upper edge of each of the pair of side walls 11 and 12, and a lower portion 14 connected to a lower edge of each pair of side walls 11 and 12. The metal tube 1 has a length six times greater than the height H of the side walls 11 and 12 or more. Each of the pairs of side walls 11 and 12 includes a high strength portion 11A or 12A and a pair of low strength portions 11B or 12B. Each high strength portion 11A or 12A has a dimension of not less than (2/3) H and not greater than 3H in accordance with measured in the longitudinal direction of the metal tube, the high strength portions that form opposite portions of the pair of side walls 11 and 12, each high strength portion has an elasticity limit of not less than 500 MPa. The low strength portions 11B or 12B interleave the high strength portion 11A or 12A with each other as determined along the longitudinal direction of the metal tube, with each low strength portion having an elasticity limit of 60 to 85% of that of the high resistance portion 11A or 12A.
